ACT! 2008 text import only brings in 1 note

I am trying to import from a text delimited file, and I map several fields as "Add to ACT! Note". However, only the last field is added as a note, the previous fields are ignored. Each contact has 5 fields of notes, and I tried importing only the first 2, then 3, then 4, etc. and each time, only the last one defined is imported. Is this a known bug, is there a workaround? Thanks.
